Description

Technical Field

[0001] The utility model relates to the technical field of cable installation, in particular to an automatic traction machine for cable installation. Background Art

[0002] The cable traction machine is a new type of wire and cable construction machine developed on the basis of the multi-functional pay-off and take-up machine. It has the characteristics of small size, flexible and convenient use, and is more suitable for cable construction in narrow road sections, especially in cities. The traction function is the same as that of the multi-functional pay-off and take-up machine. It can not only pull and unfold wires and cables, but also be used for tightening wires, erecting poles, etc.

If the adjustment is made by moving the universal wheel at the bottom, the entire device needs to be pushed and rotated, resulting in greater use intensity and reduced construction efficiency. For this reason, an automatic traction machine for cable installation is proposed. Utility Model Content
